WRENCH.

Specification of Letters Patent.

Patented May 6, 1913.

Application filed November 23, 1912. Serial No. 733,126.

To all whom 25 may concern Be it known that I, JEFFERSON W. SEALE, a citizen of the United States, residing at Mineral Vells, in the county of Palo Pinto and State of Texas, have invented a new and useful VrenCh, of which the following is a specification.

This invention has reference to improvements in wrenches, and is designed to provide a wrench which may be particularly useful for machinists, especially in posit-ions where a thin jaw wrench is needed, and in 'addition providing for the removal of parts The last-named end of the wrench, which may for convenienceV be termed a pipe gripping end, or simply a pipe wrench end, has

a movable jaw construction adapting it particularly to the use for which the wrench is intended.

The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming a part of this specification, with the further understanding that while the drawings show a practical form of the invention, it is susceptible of other practical embodiments, wherefore the invention is not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings r-Figure 1 is a side elevation of the wrench. Fig. 2 is a longitudi# nal section. Fig. 3 is a section on the line 3 3 of Fig. 1 but drawn on a larger scale. Figs. 4, 5, 6 and 7 are detail sections on the lines 1 -4, 5-5, 6 6 and 7-7, repectively, of Fig. 1, but drawn on a scale similar to that of Fig. 3.

In the drawings there is shown a wrench each in the form of an elongated fiat bar, engaging edge to edge, one of the members, say the member 1, at an intermediate point having a recess 3 formed therein on the edge engaging the other member, and lodged in this recess is an actuating screw nut 4 engaging teeth 5 on the other member, the arrangement being similar to the actuating devices employed in different types of wrenches, and especially pipe wrenches. On one end of the member 1 is formed a jaw 6 and on the corresponding end of the member 2 there is formed a jaw 7, these jaws having matching faces 8, 9, parallel one to the other and at an angle to the meeting edges of the two members 1 and 2 approximating fortyfive degrees. although this angle may be otherwise related to the meeting edges of the two members. The wrench members are preferably made quite thin.y so that the jaws 6 and 7 may be introduced in places where a thicker type of wrench would not be received and the angle of the jaws 6 and 7 to the body portion of the wrench permits .its use under conditions prohibitive to an ordinary monkey wrench.

Thatend of the member 1 remote from the jaw 6 is formed with a jaw 10 projecting oppositely with4 relation to the jaw 6 and in coactive relation to the jaw 10 is another i jaw 11 on the corresponding end of a shank 12 connected in a manner to be described to the body member 2, which latter is shorter than the body member 1, the difference in length of the two body members being made up by the shank 12 with its jaw 11. The two jaws 10 and 11 are thin and Hat like the jaws 6 and 7, and these two jaws are de signed to operate the same as the jaws of a pipe wrench, for which reason suitable teeth 18, 14 are provided on the respective jaws. It is customary in pipe wrenches to form the teeth either directly on the respective jaws or on renewable blocks attachable to t-he jaws, and in the drawings the latter expedient is shown, the teeth 13 being formed on a block 15 and the teeth 14 being formed on a block 16. Each of these blocks has wings 17 arranged to straddle the respective jaws 10 and 11 and to be traversed by screws or pins 18, which also traverse the jaws for holding the toothed blocks in place. Moreover, the jaws 10 and 11 are recessed, so that the blocks 15 and 16 may be inset for a distance into the corresponding portions ofthejaws 'x by a pin or screw 20 in turn traversing an elongated block 21 engaging that edge of the body member 1 remote from that engaged by the body member 2, the pin or screw 20 serving as a pivot, as will hereinafter appear. The legs 19 are connected to the block 21 at a point about intermediate of the length of the block. On one side of the pivot 20 the block 21 is made fast to the ends of the legs of a yoke 22 embracing the body member 1 so as to hold the corresponding end of the block 21 to the body member 1, but at t-he same time permitting relative sliding movements of the block 21 and the body member 1 lengthwise of the latter. The block 21 at the end remote from 'that carrying the yoke 22 has straps 23 made fast thereto on opposite sides of the body member 1, and these straps are ot sutlicient length to be made tast to the correspond! ing end of the body member 2, this end pose to be described, so that at the end where the straps 23 are made fast to the body member 2 the latter is of less width than the main portion of the body member 2. Projecting from the shank 12 at that edge thereof remote from the edge engaging the body member 1 is a finger 25, the diiection of projection being lengthwise of the shank 12, and this finger extends along the narrow end of the body member 2 in the recess 24. The finger 25 has fast thereto a spring 26 so related to the finger as to engage the body member 2 within the recess 24. The shank 12 is provided with a notch 2T accommodating the yoke 22 where passing over the body member 1 between the latter and the shank 12.

The straps 23 serve to hold the body meml bers 1 and 2 together at the end of the body member where the straps 23 are applied, while a yoke 28 fast to the body member 1 and embracing the body member 2 adjacent the jaw 7 serves to hold that end of the body A member 1 provided with the jaw 6 to the and 2 as to answer the purposes of an open ended wrench under conditions which would be impossible with an ordinary monkey wrench.

The pipe wrench end of the tool is adjusted by the nut 41 and when it is desirable to use this end of the wrench the jaw 11 turned on the pivot 2O by pressure applied to the finger 25, thus moving the jaw 11 away from the body member 1. Now, when the pipe gripping end of the wrench is applied to any object to be turned, the strain diie to the action of the wrench will move the jaw 11 about the pivot 2() iintilthe shank of the jaw is in engagement with the body member 1, especially at the point where the jaw and shank join, thus relieving the pivot v20 of strain. rlhe pivot 20 on the oppcsite sideyof the body member 1 from the shank 12 and therefore the movable or pivoted jaw 11 approaches the iiXed jaw more rapidly than any ordinary pipe wrench, thereby greatly reducing the liability of slipping. Should the teeth 13 and 14 become worn, new blocks 15 and 16 may be substituted for the worn ones, and the wrench is at once restored to its original efficiency.

Vhat is claimed is 1. A wrench comprising two elongated members of substantially equal length and slidable longitudinally one on the other, one member including a jaw in fixed relation thereto, and the other member including a jaw pivoted thereto and provided with a shank in normal alinement with the remainder of said second-named member, the pivot connection of the pivoted jaw to the second-named member being on the side of the first-named member remote from said second-named member.

2. A wrench comprising two elongated members connected together and movable one on the other in the direction of the length of the wrench, one of said members with a member individual thereto and eX-` tending to the side of the first-named member remote from the second-named member and jaw carried thereby and there pivotally united one t-o the other.

3. A wrench comprising an elongated member having a jaw formed on one end thereof, another elongated member connected to the first named member and slidable lengthwise thereof, another jaw in operative relation to the first-named jaw and provided with a shank having pivotal connections to the second named member on the side of the first named member remote from the second named member, and a manipulating member extending from the shank of the movable jaw along the seco'nd named member in the direction of the length thereof and from the end of the shank remote from the jaw carried by it.
